Partial absorption of the solar spectrum is one of the key limitations of dye-sensitized solar cells (DSSCs). In an attempt to address this issue, we have developed co-sensitized working electrode based dyeanchored counter electrode (DACE) DSSC strategy to achieve panchromatic absorption using multipledyes. Herein, we have synthesized a dithionopyrrole based TP–DTP dye and a porphyrin-based Y351-Sdye and explored to a new type of DSSCs modified with DACE. To realize the effect of DACE electrode onthe DSSC efficiency, we have fabricatedfive different DSSCs devices namely, S-DSSC1, S-DSSC2, S-DACE,CO-DSSC, and CO-DACE using these synthesized dyes and compared their performances systematically. In addition, the detailed impedance and stepped light-induced transient measurements of thephotocurrent and voltage (SLIM-PCV) experiments are also performed to assess the charge transferresistance and charge collection efficiency of these devices. The highest efficiency of 8.72 0.15% isobserved for the CO-DACE-based devices, which is higher than the traditional DSSCs made of single dye-sensitized (S-DSSC1 and S-DSSC2), and co-sensitized DSSC (CO-DSSC). It can be attributed to theenhanced incident photon to current conversion efficiency (IPCE) and short circuit current (Jsc) whichclearly portray the advantage of DACE electrode in harvesting maximum incident light.
